This is a COMET-funded project to develop forecast confidence measures using NCEP Ensembles. The end goal is to implement these measures for real-time use within the NWS web-based graphical forecasts. A more detailed discussion of the project and its goals, along with answers to frequently asked questions can be found here.

Please note that these products are experimental and not official forecasts. For official forecasts in the U.S., please refer to the National
Weather Service and National Hurricane Center.

Below you will find a 5-day forecast confidence map from the latest GFS ensemble run. Links to other forecast times are available below.
